Budget reports can be a useful tool for evaluating a manager's effectiveness only if they contain the appropriate information. When preparing budget reports, it is important to include in the report the items the manager can control. If a manager is only responsible for a department's costs, to include all the manufacturing costs or net income for the company would not result in a fair evaluation of the manager's performance. If, however, the manager is the Chief Executive Officer, the entire income statement should be used in evaluating performance.
